Tendons are, essentially, elastic cords stretched between two fixed ends; as such, they can support standing waves. these resonances can be undesirable. the achilles tendon connects the heel with a muscle in the calf. a woman has a 20-cm-long tendon with a cross-section area of 110 mm2 . the density of tendon tissue is 1100 kg/m3.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
